.8 mil plastic with 2 rows of slits
Constructed by installing 6-foot wide sheets of slitted plastic over wire hoops that are spaced about 4-5 feet apart. The cover is pulled taut over the hoops, and the edges of the cover are secured with soil. Generally, the cover is left over the plants for 3-4 weeks. The slits provide daytime ventilation, eliminating the need for manual venting. Low tunnels are generally used in conjunction with black plastic mulch for weed control and enhanced soil warming.
Frost protection of 2 to 4° F
Early Production of Crops
Daytime temperatures might be excessive under the cover. Under those conditions, partial removal of the cover may be necessary.
